In lore and the old Official web site (now defunct), a zone is usually referred to as a "region" (however, the community has basically forced Blizzard to start using zone instead). Furthermore, lore regions and in-game zones do not always match up (what may be a region in lore may be reduced to a subzone in-game, or some subregions may become their own zones).
